Things might get really interesting if Chelsea bring the right manager for themselves. But there isn't a definition of this in me yet.
They need to make their choice wisely about a manager. I mean that they should be careful about the strategies and tactics of that manager. If they don't match Chelsea then there is no meaning in signing him. I know that they are in a critical time period now so this is exactly why they should be careful with their choices as of now. Their chance against Real Madrid will still not be high though. But if they sign a solid manager then they can at least fight harder in this round against Real Madrid. Nagelsmann seems to be one step ahead now.
Chelsea really have a lot of great players who can build a strong team. But currently the Chelsea team can be said to have completely lost their rhythm. But agree with you, maybe if a new coach is added to the team, the team will regain its strength with new tactics.
Chelsea's players are currently mostly filled with young players who are indeed prepared by Potter for the long term. but after Potter was sacked I am not sure if the new coach who will be recruited by Chelsea will be able to make the right strategy for Chelsea. but the quality of the Chelsea players is quite good. but the problem is that young players sometimes have a mentality that is also easily shaken, especially when it's in a big competition like the Champions League. and well Chelsea needs a coach who can build strong motivation for his players to keep the players' mentality high and also of course a new strategy might also make Chelsea players have to adapt again. and actually it takes time and cannot be applied immediately with just a few practice sessions.
I think now that Potter has been fired Chelsea will begin to play good football compared to Potters regime. Chelsea is a strong club and have quality players but their problem started from when Todd took over ownership of the club.
Building Chelsea to a standard form will not be achieved so soon, and not in this season because the new coach needs to study the laxity in the players and what strategy he needs to use in playing other clubs so that victory can always be theirs. Real Madrid form is too strong for Chelsea to win in their poor form,automatically, I think Chelsea is out and should start preparing for next season UCL if possible.
